If you have some old, faded electronics or other plastic gadgets in your house, you can make them look great again with just a dab of Vaseline.

While really old and yellowed plastic might need something like Retr0bright to bring back their color, you might be able to get by with the petroleum jelly sitting in your cupboard.
